A football team lost 9 yards on its first play. It then gained 9 yards on its second play. A. What expression can be written to represent how many yards the football team is from where it started? Explain your reasoning. B. How many yards is the football team from where it started? C. Suppose that, instead, the football team had gained 9 yards on its first play and lost 9 yards on its second play. Would the team’s position on the field have been any different than it actually was after the first two plays? Why or why not?

Whoops, sorry I'm taking forever to answer, Lol, I'm helping my sister with something. :P

OpenStudy (anonymous):

hi

OpenStudy (anonymous):

hey girl

OpenStudy (kamibug):

I think for part A the equation could be: x = -9+9 For part B it would be 0 because you can solve the above equation for x and since they lost 9 yards and then gained 9 yards, they're in the same place they started. :) For part C the position would still be the same because +9-9 = 0 Hope this helps! :)
